ABSTRACT
Perinatal physiology is a field of medicine which studies the
life of an individual, human, or animal during gestation and
its preparations to adapt to a new world. This world will
demand from the individual to breathe air and obtain its
food from the environment instead of depending on the
circulatory system to perfuse an area where metabolic waste
will be disposed of and nutrients and oxygen will be acquired.
Successful transition at birth is dependent on establishment
of the lungs as the organ of gas exchange.
